The Security Service of Ukraine (SBU), in tandem with the Armed Forces, has claimed operational responsibility for a highly destructive, multi-theater weekend air campaign that bypassed the Russian capital’s elite air defenses and heavily degraded occupied infrastructure in Crimea. In a statement published to the intelligence agency’s official Telegram channel on Sunday, May 17, SBU Head Major General Yevhenii Khmara confirmed that specialized drone operators from the Center for Special Operations “Alpha” managed to simultaneously hit heavily fortified domestic manufacturing assets and frontline military airfields.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. Penetrating the Moscow defense ring While the Russian Ministry of Defense claimed to have neutralized over 550 Ukrainian drones across 14 separate regions overnight, SBU flight logs and corresponding ground telemetry confirmed that precision munitions cleanly hit several highly sensitive targets inside the Moscow region. Specifically, long-range drones directly impacted the Angstrem Semiconductor Plant in the closed manufacturing hub of Zelenograd. As one of the primary domestic suppliers of specialized microchips and semiconductors for the Russian military-industrial complex, the facility remains under strict US federal sanctions. Simultaneously, the Moscow Oil Refinery in Kapotnya suffered a direct strike that triggered a localized explosion, leaving 12 industrial workers injured and disrupting local fuel processing loops.
